1) I cannot find "File" -> "New" -> "IDE Language Support" -> "Parser
Services" -> "LPG Grammar and Parser for UIDE"
instead I get "File" -> "New" -> "IDE Language Support" -> "LPG" ->
"New LPG Grammar with Parser Wrapper".
Are these options the same thing?
2)When I proceed further using the option "New LPG Grammar with Parser
Wrapper", the package of AST remains empty (no classes/interfaces are
generated in it) and due to this I get errors in other packages...

Finally, I want to know in more clear terms how to test it after successful
completion of all the steps? (I did not understand the same in user guide)
